Political Landscapes of London

Londoners will decide on their new mayor on the 3rd of May in this year’s mayoral election. Directly elected mayors were introduced in England in 2000 when Labour candidate Ken Livingstone was elected the first Mayor of London. He therefore also became the first to have this position in England under the Local Government Act 2000 introduced by the then Labour government under Prime Minister Tony Blair. Meanwhile, other cities have followed, and more will have a referendum on the issue on the same day Londoners go to the polls this year. Continue reading

US Election 2010: Mapping Senators and Governors

The previous post on this website already featured the map of the vote share in the US Congress related to the population distribution. But beyond the House of Representatives the voters in many US states had more to decide on: 37 Senate seats as well as 37 Governors were on the ballot paper. Here are the missing maps for these elections, shown in cartogram manner again. As the Senate grants each state the same number of Senators, a population-centric projection is less useful in this case. The following map thus transforms each state to have the same space on this map, so that the senate’s power distribution is better reflected in this depiction. The map only displays the results of last Tuesday’s election to the US Senate:

Mapping the US midterm elections

Two years after Obama has been elected president, another political change has come to the United States in this year’s midterm elections. Politically most significant will be the changed balance of power in the House of Representatives, which has now a majority for the Republican party (winning 240 of the seats, compared to 186 going to the Democrats, and 9 undeclared at the time of writing). Unlike the seats in the US Senate (with still a small majority for the Democrats), the share of seats in the Congress reflects roughly a quite equal population. The congressional districts, which are the decisive constituencies for the House of Representatives, are thus reflecting a general image of the political mood in the US (while the Senate is composed of two Senators for each State, regardless of the population).
Therefore it makes sense to create a different map of the election results for the House of Representatives in order to show a population-centric view of this year’s midterm. The following map uses a gridded population projection and maps the election results onto it, so that it shows the proportional population share of the results in its true dimension: Each person on the following map has the same space, so it reflects the number of people represented by each member of congress. To see where changes took place, different shadings of red/blue have been used in addition. The map uses the same colour key as the election maps on the Guardian website – their map allows you to identify any of the States and gives further details on the results for each electoral district.
This is how the results from the election to the House of Representatives in the 2010 Midterm elections of the United States look like on a population projection (a geographical view with a conventional map is included as an inset to allow comparison with the more commonly used maps):

General Election 2010: The swings that did matter

We have seen and heard a lot about the election outcome, not only on this website (here, here, here, here and here), but one more map: The following hexagon map (see here for a comparison of the different map types we are using) shows the changes that have actually taken place in the constituencies. The colour scheme indicates where seats have changes between the parties, and where they remained the same. For a clearer picture, the national parties in Scotland (SNP) and Waled (PC) have been put together under one colour.
This map is also available as a kmz file for GoogleEarth and other compatible software, which allows to zoom in and identify constituencies (a geographical version of the map is also included in the file).
